To install the switch on a concrete wall, perform the following procedure:
1. Place the switch on a table.
2. For the AT-x550-18XTQ or AT-x550-18XSQ Switch, install the four
AT-BRKT-J24 wall brackets to the sides of the unit, with the sixteen
M4x6mm screws included with the switch. Refer to Figure 58 on page
118.
3. For the AT-x550-18XSPQm Switch, install the two wall/equipment rack
brackets to the sides of the unit with the eight M4x6mm screws
included with the switch. The brackets should be installed diagonally
across from each other. Refer to Figure 59 on page 119.
4. Have another person hold the switch on the concrete wall at the
selected location for the device while you use a pencil or pen to mark
the wall with the locations of the four screw holes in the four brackets
(one screw per bracket). Refer to Figure 61 on page 122.
Follow these guidelines as you position the switch on the wall:
 Position the switch so that the front panel is either on the left or the
right. Refer to Figure 55 on page 112. Do not install the switch with
the front panel facing up or down.
 Leave sufficient space from other devices or walls so that you can
access the front and back panels, and for adequate air ventilation.
